摘要翻译:
我们提出了一个两两竞赛族,将$k$-类分类简化为二元分类。这些约简对于二进制误差的恒定分数是可证明的鲁棒性。结果改进了PECOC构造引用{SECOC},计算量从$O(k)$增加到$O(\log_2k)$,并在遗憾依赖关系中去掉平方根,使最优计算量和遗憾匹配到常数。

英文摘要:
We present a family of pairwise tournaments reducing $k$-class classification to binary classification. These reductions are provably robust against a constant fraction of binary errors. The results improve on the PECOC construction \cite{SECOC} with an exponential improvement in computation, from $O(k)$ to $O(\log_2 k)$, and the removal of a square root in the regret dependence, matching the best possible computation and regret up to a constant.
